Where do you fine folks send your analyzers away for annual calibration and certification? My Testo 325 has been gone for over 3 weeks and I just got a quote of $450. Seems the price has doubled in the last couple years. It doesn't need any sensors, just calibration and certification.
I use a TPi 712 combustion gas analyzer. My last employer had always picked up the cost of calibration, not sure how much it cost. We sent them to Frontier Wolseley (http://www.wolseleyinc.ca/) and they shipped them to TPi.
You could try WWG Totaline (http://www.wwgtotaline.ca/), they sell the TESTO combustion analyzer.
It has been shipped and returned from WWG. Thanks
